Cricket Size

Question
My mom bought large crickets but i think my gecko should have small crickets because its only 4 months old and its 9-10 cm long.What size do you think the crickets  should be?

Answer
Without knowing what kind of gecko you have I would say smaller would probably be better...  It's not as big a deal with geckos as it is with bearded dragons but a good rule is if the crickets would fit sitting sideways on the head of the lizard the size is ok.
